Hi I'm having an issue with a Honda xl 600r. The horn when pushed makes the brake light light up and the instrument like as well. I've checked the wiring diagram and the grounds but no luck. Thanks Andy

Hi Andy, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, what year is the XL600R please? Post back with a copy of the wiring diagram to serve as common reference.

Still, proposed preliminary tries (if have not been done):

  • • re-inspect the battery, its ground lines and/or re-check and re-clean the battery cables + terminals, connectors and wiring;
  • • hardwire a secondary ground line from the battery's - terminal to the frame, engine, harness' green wire and to the headlight's ground/green wire.
